Method Detail

init

public void init()

write

public static boolean write(java.lang.String filename,
                            IServerI server)

Writing the content of server out to OBJ file. The main entry of the exporter class.

Parameters:

filename - An exporting file name.

server - A server interface containing exporting data.

Returns:

Boolean true if writing is successful. Otherwise false.

write

public static boolean write(java.io.File file,
                            IServerI server)

Writing the content of server out to OBJ file. The main entry of the exporter class.

Parameters:

file - An exporting file object.

server - A server interface containing exporting data.

Returns:

Boolean true if writing is successful. Otherwise false.

write

public void write(java.io.PrintStream ps,
                  IServerI server)

writePoint

public void writePoint(java.io.PrintStream ps,
                       IVecI point)

Exports a point object. Because OBJ file doesn't have point object, a point is exported as a line with zero length.

Parameters:

ps - PrintStream to write out.

point - Point object.

writeCurve

public void writeCurve(java.io.PrintStream ps,
                       ICurveI curve)

Exports a curve object.

Parameters:

ps - PrintStream to write out.

curve - Curve object.

checkTrimLoopDirection

public static void checkTrimLoopDirection(java.util.ArrayList<java.util.ArrayList<ITrimCurveI>> trimLoops,
                                          boolean isOuter)

writeSurface

public void writeSurface(java.io.PrintStream ps,
                         ISurfaceI surface)

Exports a surface object.

Parameters:

ps - PrintStream to write out.

surface - Surface object.

writeTrimCurve

public void writeTrimCurve(java.io.PrintStream ps,
                           ITrimCurveI trimCurve)

writeMesh

public void writeMesh(java.io.PrintStream ps,
                      IMeshI mesh)

Exports a polygon mesh object.

Parameters:

ps - PrintStream to write out.

mesh - Polygon mesh object.

writeVertex

public void writeVertex(java.io.PrintStream ps,
                        IVertex vertex)

writeFace

public void writeFace(java.io.PrintStream ps,
                      IFace face)
